I'm considering my favorite bassist's equipment now that I'm gear shopping (heyo! Financial aid!), so for further discussion. I'm considering an Ampeg SVT 4pro for my head. I really want to get a Sunn cab, but those are few and far between in these parts, so I'm considering a SWR Goliath. Thoughts?

Looking to play Death Metal, but second priority is to get some good fuzzy Doom/Sludge tone as well.

I highly recommend the Ampeg SVT 4Pro, i've gone through a lot of bass heads and this is the best one I have gotten and never felt the need to get another. And I agree with Awblaster, just get an 8x10 classic ampeg cab and your set. That's my standard set up along with an old russian green big muff pi.

I also have an Peavy 2x10/2x18 cab that I use for using just straight doom cause of the bit more low end but the ampeg cab is quite capable of handling all your needs you want. It's what I mainly use while recording everything.
